Question 1125414
<br>
The other tutor who responded often has strange ways of solving problems; I have no idea what the meaning is of the equation she shows....<br>
The usual algebraic method for solving the problem would look something like this:<br>
(1) s+f = 16  (the number of 2-point shots (s), plus the number of free throws (f) is 16)
(2) 2s+f = 18  (the total number of points is 18)<br>
Subtract (1) from (2) to get s = 2.<br>
So she made 2 2-point shots and 14 free throws.<br>
Note that  you should be able to solve this kind of problem informally, through logical reasoning.  Each 2-point shot is worth 1 more point than each free throw; if the point total was only 2 more than the number of shots, then the number of 2-point shots had to be 2.
